Do You Insulate a New Fiberglass Hood??

[bretamo]

My bitch is almost back (see photo), and I am curious with the new Cervini fiberglass hood if I should plan to insulate the underside of it.

Do you folks that have a fiberglass hood have insulation on the underside?

Thanks in advance.

its all up to you if you want to insulate it i have seen more without insulation than with insulation but alot of times you have to request the manufacturer to drill the holes needed to install the insulation or drill the holes yourself if there not already drilled some may come predrilled....

My thought about insulation is to protect the brand new paint from excessive heat.

Is the insulation needed?

Has anyone WITHOUT insulation had their paint job ruined?

Didn't hurt my paint from heat when i had it painted
2 1/2 cowl hood and 351 in there so even closer to hood

Vast majority of glass hoods are not insulated, you want to drive the car with the hood unpainted for a few months to cure the glass and prevent bubbling. Far too many hoods I've seen were painted too early and as the chemical released from the fiberglass the paint bubbled. It's not the heat that ruins the paint, it's the chemical release as it cures.

Oooooops, it might be too late for me.

My Cervini hood came right out of the box to the paint booth. It maybe had a little bit of Florida heat applied to it, but nothin more than 100 degrees of heat.

well just hope for the best...mine did bubble but only VERY slightly on the drivers edge and not worth addressing yet, unfortunately some damage with a small drill bit means she will be painted sooner than later.

Rather than insulate them I typically like to drill holes in mine.

Sorry this was of no help to the original poster, but I couldn't resist.

fiberglass is supposed to be baked prior to paint to make sure this doesn't happen. any professional paint shop should know this

 

[bretamo]

I'm kinda tick'd now. Both the body shop and CERVINI's instructions failed to inform about "baking in" of the product before applying paint.

Could it be that Cervini bakes them before shipping? Does anyone know?

LOL - I might need to borrow your drill press soon!

Seriously, after looking at the hood it seems to be begging for some hood-pins. What do you think?

 

[1991vert]

no they do not bake it prior to shipping.

There was a large orange sticker on mine that said to leave it out in the sun for a few days before painting.

I had my Cervini's 4" cowl painted about 4 yrs ago, no insulation and no paint problems either. At that time, I didn't see anything about leaving it in the sun before painting it but it was installed for a while prior to being painted too.
As for hood pins, a definate must IMO. I've read where many fiberglass hoods somehow unlatch while driving and that's a scenerio I never want to experience. Saw it happen to a car on the freeway a few weeks ago.

I'm not usually a fan of stripes on a Fox, but that red/silver combo is killer.

 

[DMAN302]

I would not run a glass hood without...many trust the stock latch but my hood did release on me once a low speed and since then she's been pinned.

I had an 80 Camaro with a fiberglass L-88 hood that came off on me while doing 60 on a rural highway. Scared the living crap out of me, and ripped the oil line out of the block which sprayed everywhere. Had pins without cables at the time and someone had stolen them, so I would recommend cables as well.

dynamat makes a product called " hoodliner" its relativly cheap and super easy to apply. and it also looks good. check it out. its got an alum. face so it really cleans up the look alot.

Thanks for the tips. I'm looking up "hoodliner" right now.

Thanks for the feedback, BlackSun, it took me a lot of thinking before I committed to that stripe.
